The name "Sage" comes from the Latin salus, which means health, and from salvea, which means salvation. Scientific studies found that White Sage has antimicrobial and antibacterial properties. Burning sage decreases the level of aerial bacteria by 94%, and the cleaning effects are preserved for up to 24 hours afterwards.
White Sage is often used for cleansing and rituals. It removes negative energy in spaces, but its applications are more extended. It has many benefits in energy healing, feng shui and the paranormal too. Also, daily life sometimes brings some negativity. Burning white sage can help clear negative energy associated with unpleasant life events in spaces such as your home or office. 
Smudging requires simple ingredients like matches, smudging herbs, and a smudging bowl. Before you start, remember to open a door or window, because the unwanted energy you are trying to clear must have a pathway to get out. First, light one end of your smudge, allowing it to catch fire and burn for several seconds. Then gently blow on the lit end - the smudge will begin to glow and smoke. Lay the smudge on a heatproof bowl to catch the ashes as it burns.
